Second-seeded UCSB (23-8), which also beat the Mustangs 86-61 on Saturday night in the regular-season finale, will play No. 3 seed UC Irvine in the semifinals on Friday.

Vincent and Heidigger each hit a 3 in the first 56 seconds and UCSB never trailed. After Ami Lakoju scored six straight points to give the Gauchos a 19-8 lead, Cal Poly's Victor Joseph hit a jumper but Heidigger answered with back-to-back 3s and the Mustangs went more than 10 1/2 minutes before making another field goal. UCSB took a 45-18 lead into the break and cruised from there.
